Backcountry Mutherload Strap – Accessory Review

Backcountry Research Brings Us The Mutherload of Straps

The Mutherload Strap from Backcountry Research provides a strong and versatile system to mount what you want, where you want it, anywhere on your frame.

Super lightweight and constructed with rugged materials, the Mutherload Strap is a simple yet very effective solution to securely strapping essential gear to your bike, and lighten the load in your pack.

Backcountry Research are a relatively small brand based in Bozeman Montana and have been making ingenious little gems like this since 2008. Backcountry Research have grown their brand slowly and solidly over the years through word of mouth. 2017 saw them co-sponsor the Yeti/Fox World Enduro team, equipping riders like Richie Rude, Cody Kelley and women’s pro-rider Anne Galyeanand.

First Impressions

There’s no denying, the Mutherload Strap is one tough cookie. Made from #92 industrial UV and rot resistant bonded polyester thread, you could literally hang a car off this thing. So don’t ever fret about it coming apart anytime soon.

The strap features a velcro tab section,  two rubber like shock rings and the whole package only weighs around 42 grams. The best designs are sometimes the simplest ones.

In terms of colours, we opted for a stealthy (some may say boring) black colour option but the Mutherload Strap comes in about 50 colours and creative patterns to choose from.

To set up is quick and pain free. Although on our first set up we did put it on slightly wrong, so the installation video was very useful, we’d recommend you watching that first.

To Load

Simply centre your inner tube on the grip-strip and pull the dual shockcords up and over the ends of the tube to lock it down…flip it over and slide in your choice of inflation, multi-tool or levers.

To Mount

Position your bundle where you want it on the bike with the tube and shock cords facing the frame. Feed the slack end through the contoured loop and reef tight.

Carrying Capacity

The Mutherload Strap has been designed to take a standard 26″, 27.5″ or 29″ tube by itself or with 1-2 16g cartridges, 1-2 20g cartridges, 1-2 25g cartridges, multi-tool, mini pump, levers or whatever combo you want. In our test we packed a 29″ tube, a 25g CO2 cartridge and two tyre levers.

Out On The Trails

Any strap system must only really pass one or two very simple tests. How much can it carry and does it stay put. Meaning, will my gear fall off at the first rock garden I hit? Well, in terms of how much it can carry, it’s pretty basic but these are essential items we are talking about. So we’re all good with only having 3-5 items. Any more and we’re heading into pack territory.

In regards to does it stay put. Well, yes it does. The Mutherload Strap has the gripping power of a barnacle on steroids. It just doesn’t move, at all! On rocky terrain, all day rides, it never budged. Un-mounting is a breeze and you can simply throw it your kit bag with all the items still attached.

On those crusty, wet and muddy rides it will get covered in grunge but washing the strap is easy. We just took it into the shower and got it lathered up and the drying time is pretty swift so it’s ready to go again in no time at all.

Born and grew up in Wales but now a fully fledged Aussie. A passionate mountain biker, hiker and general nature addict. I’m also a bit of a muso and enjoy a good craft beer every now and again (probably too often).

I hope what we do here at Tyres and Soles will inspire people to get out there and experience first hand, the natural wonders that surround them.

So, pump up those tyres, don your favourite boots. Grab a mate, a partner, a pet… and head out into nature. But tell us all about it when you get back.

  • The Kitsuma 1.5 from @ospreyaustralia is one hell of a lightweight pack. Talk about minimalism. This is it folks! It holds a 1.5 litre bladder and a single pocket for your bare essentials. 📸 @richardmcgibbon
  • The @ospreypacks Savu lumbar pack allows you to carry two bottles at once so you can keep riding for longer. The pack is compact and secure, even on the roughest trails and has excellent storage options to store all your ride essentials. @ospreyaustralia ⁣⠀📸 @richardmcgibbon ------------
  • The @pnwcomponents Loam lever and Rainer dropper post is the goldilocks of set ups. With buttery smooth motion and an incredibly light lever action, this is a premium grade system that won’t blow your budget. 😊 | 📸 @richardmcgibbon
  • We’ve been testing the new Seral, Savu and Kitsuma packs from @ospreyaustralia. All three packs offer something different and are aimed at day rides where you can carry the bare minimum such as the Kitsuma, or pack a little more with the Seral and Savu. The Kitsuma and the Seral use a bladder system. The Savu is a lumbar pack that has been designed to carry two bottles (no bladder). Whichever style of pack or riding you do, there’s now a great range to choose from. It’s good to see Osprey focusing on more mtb specific designs and what riders are looking for. 📸 @richardmcgibbon
